[Cod-bugs] Download using subversion or rsync not working

[Saulius Gražulis]

Hi, Noel,

sorry to hear that you have problems fetching the COD.

I have just tried the commands on my machine and the commands from the
documentation that you cite work.

The "connection refused" indicated that your program (client) could not
reach the necessary port on the COD server.

Possible reasons:

- your internet provider (university?) block the necessary ports for
outgoing connections, except http(s)...

you can check port blockage in several ways:

a) by using rsync to other sites (e.g. PDB) from the same computer;

b) by using rsync to the COD site from *another* computer that is less
likely to be blocked;

c) by using nmap to see what ports are open on the COD server from your
computer.

- somehow the IP number you are using ended up in a blacklist (although
we should only blacklist the IPs that try to guess ssh passwords, not
the rsync/svn users...). Could you please let us know which external IP
number you are using?

Of course you are always welcome to fetch the archive or download via
http(s), this would be a workaround in the current case.

We will think about providing Subversion access over https if the
blockers of ports persist.

Sincerely yours,
Saulius
